HUTCHINSON. — A Kansas inmate, who at one time was at the Hutchinson Correctional Facility and  found guilty on a charge of battery of a law enforcement officer, was sentenced to 10 years and two months in prison on Friday.

Officials said Douglas Anthony Kling, 30, was upset when a prison officer did not respond to his demand to file a grievance.

He made noise and began kicking the door of his isolation cell. The officer, Jason Garcia, said he tried to get Kling to calm down, but he didn’t, so he opened the cell door.

At trial, Kling chose to represent himself with the assistance of a public defender.

Kling is serving time for convictions in Marshall County for attempted murder, aggravated kidnapping, aggravated battery, aggravated assault and criminal threat. He also has a conviction for burglary in Nemaha County.
